AB  - Cracklike nanopatterned palladium surface layers have been produced by a green 
      chemistry method based on in situ electrochemical deposition-dissolution of zinc 
      (Zn-ECDD) in an ionic liquid bath. During the cathodic process, reactive Zn was 
      electrochemically deposited onto a polycrystalline Pd substrate. During the 
      subsequent anodic process, Zn was removed from the substrate through 
      electrochemical dissolution. Scanning electron microscope (SEM) measurements 
      showed that repetitive Zn-ECDD mediated by potential cycles results in the 
      nanopatterning of Pd surface layers, characterized by uniform crack appearance 
      with well-distributed concave spacings separated by nanowidth cracks. 
      Energy-dispersive X-ray microscopy (EDX) studies revealed that the nanopatterned 
      surface layers chemically contain a small amount of Zn. A mechanism based on the 
      development of stress induced by the Zn-ECDD on Pd surfaces was proposed to be 
      responsible for the nanopatterning of Pd surface layers. Electrochemical 
      oxidation of formic acid and reduction of nitrite were studied as model reactions 
      to demonstrate potential applications of the nanopatterned Pd electrode to 
      electrocatalysis and electrochemical determination of environmental contaminants. 
      Highly improved electrochemical responses were obtained on the nanopatterned Pd 
      for the two reactions, compared to the untreated Pd.
